PRINTING-PRESS.

Specification of Letters Patent.

Patented Mar. 26, 1912.

Application led May 27, 1908. Serial No. 435,277.

To all 'whom t may concern:

Be it known that I, FRANK B. La BARR, a citizen of the United States, and a resident'of Los Angeles, county of Los Angeles, and State of California, have invented certain new and useful Improvements in Printing-Presses, of which the following is a clear, full, and exact description.

My invention relates to web perfecting printing presses and particularly to the class of printing presses used for printing, numbering, punching and cutting the continuous records of autographic registers, substantially as described and claimed in the application for Letters Patent of the United States liled by England J. Barker', Matthew J. Barker and myself, March 16, 1904, Serial No. 198,468.

rlhe printed forms on autographic register records are made of different lengths according to the size of the different machines, and heretofore it has been customary, owing to the inability to properly adjust the printing presses, to use one press for printing forms of the same length and another press for printing forms of another length, thus requiring as many presses in a perfectly equipped establishment as there are different sized record forms.

The object of my invention is to overcome the difficulty referred to and enable one press to print forms of any length desired and thus dispense with the extensive equipment now necessary. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings :-Figure 1 is a side view i of the upper portion of a printing press,

showing, in dotted lines, my improvements applied thereto. Fig. 2 is a diagrammatical view, showing my improvements in side elevation. Fig. 3 is an edge view of the same in elevation.

My invention only concerns the feeding of the continuous web of paper to the printing, numbering, and punching devices, in such manner that t-he supply of paper thereto is intermittent according to the length of the form it is desired to print from. The means for obtaining this intermittent movement is independent of the printing-rolls, the revolving numbering devices, the punching mechanism and the cutting devices, which, although the arrangement thereof in the supporting-frame of the machine is slightly different, successively engage the paper the same as heretofore, and particularly as in the machine constituting the subject matter of the aforesaid application.

In the printing press shown in the drawings, the web of paper A running through the same, passes around idle-cylinders B, B, after leaving the supply roller (not shown), and then extends to and around a stationary guide roller a downward around a roller which reciprocates bodily vertically back up to a stationary guide-roller c. Guide roller c is, preferably, arranged parallel to and in.

the same horizontal plane as roller a, and from thence the web of paper A extends up to and around the impression-cylinder C, where it is printed upon by the curved stereotype form on the superimposed printing cylindcrD. After passing between rollers C and D the web of paper pursues a downward course, and passes between the cylinders E, E carrying numbering-heads, the punching dies F, G and then to and around a stationary idle-roller (Z up to and around a roller e having a vertical bodily reciprocal movement, and then said web runs in a forwardly inclined direction to and over the sharp edges of cutting-disks f'.

which divide the web longitudinally into.

record strips of the desired width.

Rollers b and e are journaled in bearings in the ends of arms g and L respectively, projecting from a suitable frame consisting of a vertically reciprocal bar II a distance below its upper end, which latter has its portions above and below where said arms branch therefrom confined by and movable in guide-lugs j, j, secured to and projecting from the inner surfaces of the sides of the supporting-frame of the machine. Arms g project rearwardly and upwardly from said frame and are, preferably, longer than arms z, which extend forward in a horizontal direction, substantially as shown. The lower portion of bar H comprising said frame extends a sulicient distance below the lower lug j, and is surrounded by a coil-expansion spring I, whose lower end is engaged by a thumb-nut J that retains it in place and, when desired can be manipulated so as to regulate the tension of said spring. These frames are reciprocated by means of pitmen 7c, the lower ends of which are pivotally secured thereto about at thepoint where the arms g and 7L project therefrom, and Whose upper ends are pivotally connected to levers K of the third class. These levers are fulcrumed to the inner surface of the sides of the supporting-frame at the end opposite that to or near which pitman 7c is connected, and it is engaged, mediate-its ends, by a cam L secured on the journals of the impression cylinders C next their bearings. The periphery of these cams correspond to the curvature of an evolute whose ends are connected by a more or less abrupt shoulder, and engage a suitable friction-roller m that is journaled on a stud secured to and proj ecting laterally from said levers. The upper ends of pitmen lo are also journaled on studs N projecting from levers K, but these studs extend through and are adjustable longitudinally in longitudinal slots P in levers K, which extend from the rear ends thereof to or past the friction rollers m.

In operation when the pitman is pivoted to the rearmost point of possible connection with levers K, the frames will be given their greatest reciprocal movement and will carry roller Z) downward so as to unreel paper enough to provide the necessary slack to print the shortest form that may be mounted on the printing-cylinder D. Vhile the type is engaging the web of paper it will be drawn forward, but when the type has passed out of engagement with the paper the forward course of the latter is halted by the downward course of roller b and roller e long enough to compensate for the passage ofthe unoccupied surface of the printing cylinder or for the time between the departure of the rear end of the form from the paper to the engagement of the same by the front edge of the form. By moving the point of connection of the upper end of the pitman forward on the lever the movement of the take-up rollers b and d will be less and less slack will be taken up and less slack will be required the longer the printing form is on the cylinder.

I do not wish to be confined to the exact arrangement of the printing-cylinders, the numbering-heads, the punching-devices nor the cutting devices, nor to the means shown for operating and making these functional elements properly dotheir work, for any rearrangement of them or any change in their mechanical make-up I consider as coming within the scope of my invention if used in conjunction with my improvements as hereinbefore described and claimed.

Vhat I claim as new is 1. In a printing press the combination with the printing cylinders, of a take-up roller bodily reciprocal at right angles to its axis across the path of the continuous web of paper before it reaches said cylinders, a similar take-up roller simultaneously bodily reciprocal at right angles to its axis across the path of said web after it leaves said cylinders, vertically reciprocal bars having arms projecting therefrom in which said take-up rollers are journaled, cams on the shaft of one of said cylinders, levers engaged by said cams, and pitmen connecting said levers and bars.

2. In a printing press the combination with the printing cylinders, of a take-up roller bodily reciprocal at right angles to its axis across the path of the continuous web of paper before it reaches said cylinders, a similar take-up roller simultaneously bodily reciprocal at right angles to its axis across the path of said web after it leaves said cylinders, vertically reciprocal bars having arms projecting therefrom in which said 'take-up rollers are journaled, cams on the shaft of one of said cylinders, levers having longitudinal slots therein engaged by said cams, and pitmen connecting said levers and bars and having a longitudinal adjustable connection in the slots of the former.

3. In a printing press the combination with the printing cylinders, of a take-up roller bodily reciprocable at right-angles to its axis across the path of the continuous web of paper before it reaches said cylinders, a similar take-up roller bodily reciprocable at right-angles to its axis across the path of said web after it leaves said cylin ders, common supporting means in which said rollers are journaled, a lever directly actuated by said cylinders, and a pitman connecting said lever and means the pivotal connection of the pitman with said lever is adjustable longitudinally on the latter.

4. In a printing press the combination with the printing cylinders, of a take-up roller bodily reciprocable at right-angles to its axis across the path of the continuous web of paper before it reaches said cylin-` ders, a similar take-up roller bodily reciprocable at right-angles to its axis across the path of said web after= it leaves said cylinders, a reciprocable frame in which said rollers are journaled, a lever directly actuated by said cylinders, and a pitman connecting said lever and frame the pivotal connection of the pitman with said lever is adjustable longitudinally on the latter.

ln testimony whereof I have hereunto set my hand and seal this 27th day of April, A. D. 1908.
